Recently have a strange problem:

C:\DOCUME~1\vvijay\LOCALS~1\Temp\scantmp.gdf created
py loading: g.makeFromGDF('C:\DOCUME~1\vvijay\LOCALS~1\Temp
\scantmp.gdf')
GO error: Traceback (innermost last):
File "<string>", line 1, in ?
java.io.FileNotFoundException: C:\DOCUME~1
vijay\LOCALS~1\Temp\scantmp.gdf (The filename, directory name, or
volume label syntax is incorrect)

This only happen to two persons in our group. The problem is

PythonInterpreter pi =
(PythonInterpreter)Guess.getInterpreter();

pi.exec("g.removeComplete(g.nodes)");
String gdf_script = "g.makeFromGDF('"+fileg+"')";
System.err.println("py loading: "+gdf_script);
pi.exec(gdf_script);

The character after "C:\DOCUME~1\" is changed. I thought it is "\v"
problem. But some "!!" error characters added in other person's case.
Basically the file name problem.

The program works fine when I use different temporary directory name
by

-Djava.io.tmpdir="\Temp\"

on command line.

It seems each time after posting, I find solutions. The file separator
string need to be forward slash instead of back slash when send to
Python.

But why it works on most of computers?
